Body odor can be a sign of an illness, so check with your doctor if you are concerned. Your sweat doesn't actually smell, but bacteria on your body combined with sweat can have an odor. For an effective homemade deodorant recipe, you'll need to stay dry and you might need to kill bacteria as well.
DIY deodorant recipes use arrowroot powder, corn starch, or baking soda to absorb perspiration. Baking soda will also absorb odors, but it can irritate the skin.
Tea tree oil is a great natural antibacterial essential oil, but it does have a medicinal smell. You can cover it with other essential oils.
DIY Homemade Deodorant Recipes
Which one is best for you? That depends on your body chemistry, how much you sweat, and your personal preference. If you don't experience body odor unless you exercise, then you may not need tea tree oil. But if you notice that your pits stink while working or doing everyday activities, then maybe you need the tea tree oil.
